Description

Perennial. Inflorescence a spike-like head of numerous tightly-packed racemes on an elongated axis. Spikelets 2-3-flowered; lowermost fertile, second floret male or sterile, the uppermost reduced to an awn; laterally flattened, alternate in 2 rows, disarticulating above the glumes. Glumes subequal, 1-nerved, membranous, as long as the spikelet and enclosing the florets, shortly awned. Fertile lemma much shorter than the glumes, membranous, entire and acute at apex, with a long flexuous terminal awn.
